TWO SPECIES OF ACULEATE HYMENOPTERA NEW TO BRITAIN. 

 BY EDWARD SAUNDERS, F.L.S. 



GoLLETES MONTANUS, Mor., Fedtschenko. Turk. Mellif., ii, 1876, p. 262. 



Three males and a female of a Collefes, wtich I believe to be 

 referable to this species, have been taken by Mr. A. A. Dalglish on 

 Irvine Moor, near Glasgow. It is very distinct in both sexes from 

 any of our other species, but it resembles Daviesanus in its shining 

 abdomen, and the somewhat sparse puncturation of the basal segment. 

 It is closely allied to a continental species, viz., alpinus, Mor., but the 

 ^ is very distinct from it in tlie form of the 7th ventral segment, 

 which in ononta/nus is produced into two long, parallel-sided, processes, 

 slightly spatuliform at their apices ; whereas in alpinus the processes 

 are very long and acute, and delicately membranous ; the ? is dis- 

 tinguishable by the much stronger puncturation of the basal segment 

 of the abdomen, the bright fulvous pubescence of the thorax, and the 

 wider, more transverse, face. It may be briefly characterized as 

 follows : — 



(J . Black. Vertex of the head and the thorax above clothed with fulvous 

 hairs, face below the antennee and thorax beneath, and on the sides of the meta- 

 thorax, with white ; 4th and following joints of the antennae sub-equal ; 3rd shorter 

 than the 4th. Mesothorax shining, largely punctured, wings hyaline, nervures 

 brown, basal area of the propodeum shining, and very coarsely clathrate, legs black ; 

 abdomen shining, punctured, the punctures strong but not very close, clothed on the 

 basal segment with long, somewhat sparse, pale hairs, on the others with shorter 

 black hairs, each segment with a rather narrow apical band of pale hairs, segments 

 beneath punctured, 6th ventral simple, not dentate at the sides, with a few erect 

 hairs near the apex, 7th ventral as described above ; stipites of the armature with 

 the lacinia in the form of an elongate triangle, concave, pale, and submembranous 

 in the centre, densely fringed with long hairs along the sides and at the apex,sagittEB 

 widened and angularly dilated at the base, as in marginata. 



5 . Black. Face transverse, but not so wide as in Daviesanus, clothed with 

 whitish hairs, vertex and thorax above with bright fulvous, beneath and round the 

 sides with pale whitish. Clypeus very largely and coarsely punctured, and longi- 

 tudinally rugose, its apex truncate and slightly emarginate, with two little pubescent 

 fovese just within its margin, cheeks between the mandibles and eyes considerably 

 longer than in Daviesanus. Antennae with the 3rd joint rather longer than the 4th, 

 which, like the following joints, is transverse. Mesothorax shining, strongly 

 punctured, propodeal area shining, strongly clathrate. Abdomen coal black, shining, 

 basal segment rather strongly, but not very closely punctured, clothed with long, 

 pale, almost grey hairs, the 2nd with scarcely any erect hairs, the others with black, 

 the basal segment has a few short white hairs on each side at the apex, but no dis- 

 tinct band ; the 2nd has a very narrow band of white hairs at the base and apex, 

 both sli'^htly narrowed in the middle, the 3rd, 4th, and 5th have each an entire
